The invention discloses a truss type supporting structure of a heavy full-revolving crane of a fan installation ship, the structure comprises five main chords and a plurality of horizontal branch chords, and the five main chords enclose a platform body structure with a rectangular cross section; the outer surface of the platform body structure comprises four vertical surfaces; a plurality of horizontal branch chord members are arranged between the adjacent main chord members of each vertical surface; the horizontal support chord members positioned on the same horizontal plane form a horizontalsupport chord member group; horizontal inclined supporting rods are arranged in a rectangular area defined by the horizontal supporting chord member groups; inclined support chord members are arranged between the horizontal support chord members which are adjacent up and down, between the uppermost horizontal support chord member and the upper shell, and between the lowermost horizontal support chord member and the lower shell; and the inclined support chord members are distributed on the vertical surface. The weight of an empty ship is greatly reduced, and the variable load of a deck is effectively controlled; the wind resistance area is greatly reduced, the ship stability is effectively improved, and the ship comfort is improved; and construction is simple, and the construction cost canbe effectively controlled.
本发明公开了一种一种风机安装船的重型全回转起重机桁架式支撑结构,其包括五个主弦杆和多个水平支弦杆,该五个主弦杆围成横截面为矩形的台体结构;该台体结构的外表面包括四个竖向面;每个竖向面的相邻主弦杆之间均设有多个水平支弦杆;位于同一水平面的水平支弦杆形成一个水平支弦杆组;水平支弦杆组围成的矩形区域内设有水平斜撑杆;上下相邻的水平支弦杆之间、最上方的水平支弦杆与上壳体之间、最下方的水平支弦杆与下壳体之间均设有斜向支弦杆;斜向支弦杆分布于竖向面上。本发明大幅度减轻了空船重量,有效控制了甲板可变载荷;大大减小风阻面积,有效改善船体稳性,提高船体舒适度;施工简单,可以有效控制建造成本。
